Module Decisions

Introduction

There are many ways of doing one thing in programming. Instead of getting into debates about the one right way of doing things, in fastai library we would like to make decisions and then stick with them. This page is to list down any such decisions made.

Image Data

• Coordinates
• Computer vision uses coordinates in format (x, y). e.g. PIL
• Maths uses (y, x). e.g. Numpy, PyTorch
• fastai will use (y, x)
• Bounding Boxes
• Will use (coordinates top right, coordinates bottom right) instead of (coordinates top right, (height, width))
